Abstract (en)
[origin: EP0733835A2] The inner surface (6) of the profiled elastomeric seal has two sealing lips (7,8) sealing the outside of the slide plate (5). Between the sealing lips is a stable, thermoplastic guide belt containing filler (9) whose inner surface cooperates with the slide plate. The circle-segment-shaped lower outer defining surface (11) of the profiled seal matches the external circle segment shape of the profiled seal interior (2). Under and behind the lower sealing lip (7) is a cavity forming a pressurised chamber (12) together with the slide plate. The lower, outer defining surface (13) of the pressure piece (4) fits tightly on the upper outer surface (14) of the profiled seal. Between the lower (15) and upper (16) inner surface of the profiled seal is a gap (17).
